Syntheses of (R)- and (S)-3-methylheptanoic acids

Starting from chiral methyl molecules 3 and 4, both derived from (R)-4-methyl-δ-valerolactone, we have accomplished the synthesis of (R) and (S)-3-methylheptanoic acids. Our methods are amendable to the syntheses of a wide variety of chiral 3-methyl alkanoic acids. Both enantiomers of 3-methylheptanoic acid have been synthesized from chiral methyl molecules which were derived from (R)-4-methyl-δ-valerolactone (5). A wide variety of chiral 3-methyl alkanoic acids can also be synthesized by the methods described herein.

Synthesis of all the stereoisomers of 6-methyl-2-octadecanone, 6,14-dimethyl-2-octadecanone, and 14-methyl-2-octadecanone, the components of the female-produced sex pheromone of a moth, Lyclene dharma dharma

All of the stereoisomers of the components of the female-produced sex pheromone of a moth, Lyclene dharma dharma, were synthesized. They are (R)- and (S)-6-methyl-2-octadecanone, (6R,14R)-, (6R,14S)-, (6S,14R)-, and (6S,14S)-6,14-dimethyl-2-octadecanone, and (R)- and (S)-14-methyl-2-octadecanone. Enantiomers of citronellal and methyl (S)-3-hydroxy-2-methylpropanoate were the starting materials, and olefin cross metathesis was employed as the key reaction.

Regio- and stereochemical study of sex pheromone of pine sawfly; Diprion nipponica

Regio- and stereoisomers of 1,2,ω-trimethyldecyl propionate (ω = 5-9) were prepared from stereochemically pure chiral building blocks as sex pheromone candidates of a pine sawfly; Diprion nipponica. Among the synthesized candidates, (1S,2R,8S)-1,2,8-trimethyldecyl propionate was found to be the sex pheromone of D. nipponica, based on compatibility of its GC-MS data with that of the extract of females, and its significantly high pheromone activity in a field bioassay. The field bioassay of the synthesized compounds also revealed that (1S,2R,SR)-1,2,8-trimethyldecyl propionate, (1S,2R,7S)-1,2,7-trimethyldecyl propionate, and (1S,2R,6S)-1,2,6-trimethyldecyl propionate could attract male sawflies to some extent as pheromone mimics.

Pheromone synthesis, CXCII. - Synthesis of all the stereoisomers of 10,14-dimethyloctadec-1-ene, 5,9-dimethyloctadecane and 5,9- dimethylheptadecane, the sex pheromone components of the apple leafminer, Lyonetia prunifoliella

All of the stereoisomers of 10,14-dimethyloctadec-1-ene (1), 5,9- dimethyloctadecane (2) and 5,9-dimethylheptadecane (3), the sex pheromone components of the apple leafminer (Lyonetia prunifoliella), were synthesized by starting from the enantiomers of ci

Pheromone synthesis, CLXXIV: Synthesis of (5R,11S)-5,11-Dimethylheptadecane and (S)-2,5-Dimethylheptadecane, the major and the minor components of the sex pheromone of the geometrid moth, Lambdina fiscellaria lugubrosa

(5R,11S)-5,11-Dimethylheptadecane (1), the major component of the female-produced sex pheromone of the western hemlock looper (Lambdina fiscellaria lugubrosa), was synthesized by starting from the enantiomers of methyl 3-hydroxy-2-methylpropanoate (3). (S)-2,5-Dimethylheptadecane (2), the minor and synergistic component of the pheromone, was also synthesized by starting from (S)-citronellol (4). VCH Verlagsgesellschaft mbH, 1996.
